WINDOW-CLEANING DEVICE.

To all whom it 'may concern: Y v

Be it known that I, FREDERICK W. Voon- HULL, a citizen of the UnitedStates, residing in the city andcounty of Philadelphia, State ofPennsylvania, have invented a new and useful lVindow-Cleaning Device, ofwhich the. following is a specification.

My invention consists of an improved device for wiping the windows of.locomotive cabs, street car .vestibules, automobile windshields'orsimilar windows from within and without'the necessity of opening thewindow or getting out of the vehicle.

gl. It further consists of improved means for 1moving the wiping-bartoward and away from the glass pane.

It further consists of other novel features of construction, all as willbe hereinafter fully set forth.

` For the purpose of illustrating my inven.

tion, I have shown in the accompanying drawings one form thereof which1s at present preferred by me, since the same has been found in practiceto give satisfactory and reliable results, although it is to beunderstood that the various instrumentalities of which my inventionconsists can be variously arranged and organized and that my invention`is not limited to the precise arrangement and organization of theseinstrumentalities as herein shown and described.

Figure 1 represents a front elevation of a window and its frame providedwith my improved window cleaning. device, seen from the outside. Fig. 2represents a.' similar view from the inside of the window.

' Fig. 3 represents a horizontal section on the line .fbm in Fig. l.Fig. 4 represents a vertical section on the line g/-g/ in Fig. 1. Fig. 5represents a perspective detail view of a part of the hanger. Fig. 6represents an elevation of a window and its frame illustrating adifferent arrangement of the hanger. Fig. 7 represents a top view ofanother form of my device. Fig. 8 represents a detail view of aconnection for obtaining parallel movement for the arms supporting andactuating the wiper-bar'and for providing yielding support for the same.Fig. 9 represents a lsectional detail View of the pivot connection foran arm and the bracketv on the wiper-bar.

Similar numerals of reference indicate corresponding parts in thefigures.

Referring to the drawings; the reference numeral 1 indicates the windowframe, in which the sash 2, of the window-pane, 3, is mounted. Abracket, 4, is secured to the window-frame or other support, at asuitable point with respect tothe window-pane, and is formed with twovertical sleeves, 5 and 6, in its projecting portion. Bolts, 7 and 8,'pass through said sleeves, and the ends, 9, of the links, 10, arepivoted upon the ends of said bolts. The opposite ends, 11, of saidlinks are pivoted upon'the ends of bolts, 12, passing through sleeves,13 and 14, in a bracket, 15, projecting-from a bar 16, upon the end of ahorizontal sleeve, 17. A rockshaft, 18, is journaled in said sleeve andhas a hand-lever, 19, secured to one end, which lever may be engaged andheld away to one side of the window by a hooked catch, 20. Thehorizontal sleeve 17 passes through the window-frame or other support,and has on its end a supporting arm 21, secured to it. An arm 22, issecured to the end of the rockshaft, and a second arm 23 is pivoted upona bolt or stud 24, projecting from the end of the supporting arm 21. Theoppositeends of said arms are pivotally connected with the bracket 26,as here shown by studs 25, said bracket carrying a wiper-bar l27 whichis thus held in its proper position in relation to a window-pane when itis moved over the face thereof.

The method of operating this device is substantially the same as that ofthe device for which application No. 610,218, was filed by me on the23rd day of February 1911. When it is desired to wipe rain, snow, sleet,or whatever may be deposited upon the window-pane' from the same, thehand-lever 1s released from its catch, and after'rocking it and therock-shaft to bring the wiper-bar clear of the Window-frame and sash,the hand-lever is pulled toward the operator, swinging the links anddrawing the wiperbar against the window-pane, whereupon the hand-leveris swung transversely, causing the wiper-bar to move `over the face ofthe pane, thus cleaning the same. The outer side of the bracket upon thewiper-bar 1s rounded as at 28, and the holes, 29. through which thepivot-bolts for the arms pass, are

rounded or flared toward bothA sides, so thata certain amountI of playis provide for the wiper-bar, as illustrated in Fig. 9.

In the form ofthe device illustrated in Fig. (l, the arms and wiperbarare on the same side of the window as the links, one arm being securedupon the rock-shaft. and the other arm being pivoted upon a bolt,30,secured in a screw threaded hole, 31, in the end of the bar 16 upon thehorizontal bearing-sleeve 17. The hand-lever secured upon theOppositeend of tlie1.ockshaft. The operat-ion of the device tbe same asthat of the first-described device.

In the form of the device illustrated in Fig. 7, the movable ends of thelinks are pivotedupon boltsl 32, passing through webs, 323, connected bya bar. 31, and having transverse bearing-sleeves, S5 and 36 at theirends.

'Ihe bearing sleeves 533 are fitted upon thek rock-shaft and the arm 2Qsecured upon v shaft between said sleeves; A short shaft 3T rocks in thesleeves 3G, and tbe arm Q3 is secured upon said shaft. In thisconstruction the rock shaft 1S, alone, passes through the window frameor other support and has tbe'hand `lever 19 secured thereto as before.

To provide resilient supportfor '-the,l bracket and wiper bar inthe'shght rocking motion perrvnitted the same'by their construction andconnection illustrated in Fig. 9, the device illustrated in Fig. S ofthe drawings is employed. link. 3S, is pivoted at itsv ends to the twosupporting arms and 2, a distance from thepivoted -ends of the samoandallatsprmff, 39, 1s pivotallv connected to thev bracketl and to said4link to have swinging movement parallel to the arms, but so asto admitof, but oppose, rocking motion of the bracket. lVhen the wiper-bar isbrought against. the window-pane, and theflatter is not in a planeparallel to the plane of movenient of tbe arms, the rounded surface ofthe bracket, the flared bolt-holes in the sameI and the yielding ofspring 39 will permit the wiper to adjust itself to bear with its entireedge against such pane.

the spring will cause it to resume its normal position parallel with thewindow frame.. The spring will also prevent rattling at the jointsbetween the bracket and the ends of the arms, when the wiper-bar swingson the bolts, thus relieving thelatter from, sudden shock.

The wiper-bar. will be kept out of contact with the window-pane and willnotobstruct view through the same when 'notin use, and may be drawn intocontact with the pane and exert greater or less pressure upon the sameby drawing more orless .upon the hand-lever in moving the sametransversely.

The device is applicaole to windows of In said device, a.

IVhen the wiper bar 1s removed from Contact with the glass,`

locomotive cabs, and of thel vestibules .of

d street-cars, to ordinary car-windows, towindows of carriages, -towind-shields of automobiles, or to any windows or similartransparentcontrivance from which. it is desired te wipemoisture, or anyother obstructlon tberefrol'n. The device is operated from within,without' manipulation of the window. It will be noticed that the pivotedlinks providea substantially rectilinear movement ofthe rock-shaft andof the arms and wiper-bar, so that the latter will be brought .squarelyagainstl the window-pane to bear equally against the same at allpoints.. In the several forms disclosed, the same parallel movement isprovided 'by means of th Aparallel links.

Attention is directed to the fact that only one small hole or opening,in the support, is necessary, through which the complete operation andcontrol of the wiper bar is accomplished. Any suitable 'means forconnecting or supporting the device with respect tol a wind shield in anautomobile may be employed.

Having thus described my .invention what lI claim as new and desire-tosecure by Let ters Patent.'is: .4
